摘要:
A sealing glass is provided that includes SiO2, Al2O3 having a content of less than 2% by weight, is free of PbO except for unavoidable impurities, a coefficient of linear thermal expansion (∝20-300 of more than 10*10−6/K, a dielectric constant (εr) in the range from at least 7.10 to not more than 7.80 at a measurement frequency of 1 MHz and a temperature of 25° C., and a glass transition temperature (Tg) in a range from 400 to 550° C.
